In agricultural production , the use of fertilizers through the leaves become increasingly popular with many farmers, it is considered as one of the technical measures to help increase productivity and quality of a crop effectively.
Crops need many nutrients for growth and harmonious development, high yield and agricultural products in good quality, but most farmers only notice to apply macronutrients such as nitrogen (N), phosphorus (P
2O
5) and potassium (K
2O). Also, not all of foliar fertilizers contain complete composition and concentration of nutrients needed for crops, resulting in nutrient imbalance , due to excess fertilizing or lack of one or more certain elements, especially trace elements, sometimes the use of fertilizer ineffective or counter-productive.
